i didn't do any official coast down testing, but there's a stretch of road close to my parents house where the speed limit goes from 70 to 50 km/h so i usually push the clutch and start eoc at the 70 sign and bumpstart when the cars doing 50 and look at take trafic signs and items i know as a reference....

not exact by any means but if notice a can coast "beyond the end of the hedge" i know something should be working...

i haven't filled up again after i installed the last mods, so i can't say much about their efficiency appart from that they "feel" ok, for whatever that's worth. the last two coastdowns i did on that stretch where above average so that's good (i've had mods wich seemed to slow me there so these went out of the window)

the second dams are still under revision so i might alter or ditch them if i get an indication they're not helping or could be better
